Love the Orange!

This rock appears to be a type of agate or jasper, possibly with some opaline or chalcedony inclusions. Here's a breakdown of its features:

Coloration: The rock has a mix of warm colors, including orange, yellow, and brown, which are typical of agates and jaspers. These colors often come from iron oxide inclusions.
Translucency: The orange and yellow areas seem somewhat translucent, which is characteristic of agate or chalcedony.
Texture: The surface texture appears smooth and polished, which is common in agates that have been naturally or artificially polished.
Banded Structure: The different bands of color suggest a layered formation, which is typical for agates. This banding forms from the deposition of silica from groundwater in cavities of volcanic rocks.

Given these characteristics, it's likely an agate with inclusions or banding that gives it an opaline appearance, but it's not a typical opal which would show more of a play-of-color.
